The file 'Terminator Lamp Hand Tubes 2 – Fixed Model 3D Printer Model' is (STL) file type, size is 3.8MB.
The original model has those tiny srew-imitating parts which are separated from the rest. Cura handles that well, but no way to slice it in Simplify3D, so here you've got a solution.
Fixed with Meshmixer, then reduced.
